    disk encryption

    I'd like to encrypt my disks. My problem is that I've installed Gentoo at school to show my Comp. Sci. teacher how good it is, but there's this kid that keeps booting into it with a livecd and changing the root password. I'm going to password-protect grub, so he can't just change into single-user mode, but he still has his live cds. I don't know how feasible this is, especially if I want to keep what I have on my disks. It would be a pain to reinstall what I have already, since the school has a slow (read 2-5 kbps) connection.
    Many thanks in advance.

    Pull the hard drive out of the machine and take it home with you.
    Other than that I don't think there is anything you can do to stop him from changing your pass word.

    Heh...can't really do that. It's a school disk, and windoze are on it too--it's a dual boot. Are you sure there's absolutely nothing? Thanks for the quick reply, though.

    maybe you could change 'root' to something else. Create a user with the same rights as root and in the same group then remove the root user :P

    never ever ever use the hardened option in make.conf!

    Find the person that is doing this and beat him up
    Or you could just ask him to stop.

    I have repeatedly asked him to stop, and it hasn't worked. Are you saying there's no way to secure Linux from a locally-based attack? It just doesn't seem like something Linux would leave out....

    I didn't even think about that.
    Set a BIOS password
    Change the boot order, so it boots to the hard drive first
    That should fix it.

    was a totally random flash of inspiration that i had! I seem to get them every now n then!

    Like i remember someone wanting to make it so their family couldn't see docs in the user's home dir, but they all use the same logon etc, so as a flash of inspiration, i asked... do the others know how to use CLI? Answer: No, solution to problem, stick a . at the start of the folder name hehe, making it a hidden folder so it dont show up in konqueror or nautils or like

    unless they know to add a -a to ls , can anything be truly hidden sans encryption?
